What you'll learn

State the Law of Sines: a/sin(A) = b/sin(B) = c/sin(C)
Apply the Law of Sines to solve for missing sides when given two angles and one side (AAS or ASA)
Apply the Law of Sines to solve for missing angles when given two sides and a non-included angle (SSA)
Recognize and analyze the ambiguous case (SSA), determining whether zero, one, or two triangles exist
